4.2 Batteries
4.2.1 Operating Principles
Charging / first-time
use
• The battery must be charged prior to using it for the first time because it is delivered with an energy
content as low as possible.
• The permissible temperature range for charging is between 0°C to +40°C/+32°F to +104°F. For
optimal charging we recommend charging the batteries at a low ambient temperature of +10°C to
+20°C/+50°F to +68°F if possible.
• It is normal for the battery to become warm during charging. Using the chargers recommended by
GeoMax, it is not possible to charge the battery if the temperature is too high.
• For new batteries or batteries that have been stored for a long time (> three months), it is effectual
to make only one charge/discharge cycle.
• For Li-Ion batteries, a single discharging and charging cycle is sufficient. We recommend carrying out
the process when the battery capacity indicated on the charger or on a GeoMax product deviates signif-
icantly form the actual battery capacity available.
Operation / Discharging • The batteries can be operated from −20 °C to +55 °C/−4 °F to +131 °F.
• Low operating temperatures reduce the capacity that can be drawn; high operating temperatures
reduce the service life of the battery.
